DOMENICO M. DAVINO, OF NEW YORK, N. Y.

WINDOW CONSTRUCTION.

Specification of Letters Patent.

Application filed May 11, 1917. Serial No. 167,886.

To all whom it may concern;

Be it known that I, DOMENICO M. DAVINO, a subject of the King of Italy,and resident of New York, in the county and State of New York, haveinvented certain new and useful Improvements in WVindow Construction, ofwhichv he following is a specification.

, Thisv invention relates to window construction, and it has particularrelation to that class of such constructions whereby the suspensioncords of the sashes can be readily and conveniently renewed withoutdismembering any part of the window frame and without removal of thesash from its normal. operative position within the frame.

It is the object of my invention to provide aHsimple and improved windowconstruction of the class described which will, in its adaptability foraccess to the sash suspension cords, possess advantages in point ofsimplicity and inexpensiveness in construction, surface appearance,convenience, effectiveness, ease of operation, and general efficiency.

In the drawings- Figure l is a face view, partly, in section, of awindow construction having my improvements.

Fig. 2' is a detail horizontal cross-section, on the line w-m, Fig. 1.

Fig. 3 is' a detail perspective view of the face closure for the sash atthe cord recess.

Corresponding parts in all the figures are denoted by the same referencecharacters.

Referring to the drawings, 1 designates thehwindow frame, which may bein the mainof any usual or adapted construction comprising the verticalside pockets, 2 -2, within which the weights operate in their verticalline of travel, and having at the face of the inner wall, 3, of the sidepocketed portions the projecting vertical. strips, 4, between which thesashes are retained and guided in their verti al line of travel, theinner wall 3 being also provided near the top with the usual slot, 5,for the passage of the suspension cord in its mounting over the pulley,6, which is carried internally of said wall and constitutes thesuspension means for the cord and gravity weight.

The textile suspension cords, 7, and the gravity wei hts, 8, are of anyusual construction, and in the usual operative relation as acounterbalance for the respective sashes. The window sashes, 9, are inthe andaffording access thereto.

main of any usual or adapted construction slidably operative within-thewindow frame between guide strips 4:, and the side stiles of the sashesare provided with the usual groove, 10, in their outer edges, for theaccommodation of the suspension cord and terminating at the point atWhichthe terminal end of the cord is connected to the sash.

, In connection with the conditions of window construction in which myinvention and improvements are designed to be employed, access isafforded to the weight pockets 2, and for this purpose the inner wall 3of the window frame may be provided with a sec tion at the lower end ofthe weight po kets, as at 11 (Fig. 1), which can be opened to expose theweights and the terminal ends of the suspension cords which areconnected therewith. Y

My improvements have particular relation to the means for affording.convenient access to the terminal endsaof the suspension cords, toenable the securing thereof to and their detachment from the sash, whilethe'sash is. in normal operative position and without removing the samefrom the window frame. To these ends, my improved construction for thispurpose comprises a recess, as at 18, provided at a suitable pointinternally of the side stile of the sash and opening outwardly at theface of the latter, as at .19. Said recess also has a channel, as at 20,extending upwardly internally of the stile of the sash and intersectingthe bottom of the sash edge-groove 10in which the suspension cordextends.

The closure provided for the face opening 19 of the recess 18, to avoidany impairment of the appearance or surface conditions at the face ofthe sash stile, comprises in my improved construction a plate, 21,secured. in countersunk positionati-the face. of thestile and extendingon the surface plane thereof, and having an opening, 22, registeringwith the internal recess 18 Said face plate 21 may be finished uniformlywith the sash surface so that it does not impair the facial appearancethereof. Means are further provided for closing the access opening 22 ofthe plate 21, so that the sash stile will present substantially a normalappearance notwithstanding the construction whereby access is affordedto the suspension cords, and the improved construction for this purposecomprises a plate, 23, which is pivotally mounted, as at 24, in acorresponding recess formed in the sash stile beneath the face plate 21and opening at the inner edge of the stile, said pivoted platepreferably also having an extension or wing, 25, projecting at rightangles to its main portion and accommodated in a corresponding recess atthe inner edge of the sash stile, which extension is adapted to beengaged by the .finger of the operator to swing the pivoted plate 23from its normal position and thus expose the internal recess 18 whichforms a socket for the terminal end of the suspension cord. The pivotedplate 23 is fulcrumed at its bottom, as herein shown, and the axis ofthe fulcrum is such that the plate will retain its normal position as aclosure for the opening 19 in the face plate 21, in which position thepivoted plate is concealed beneath the face plate and the generalappearance of the face of the sash stile is substantially the same as ifthe sash embodied no construction for affording access to the suspensioncord.

In a window provided with my improved construction, to renew thesuspension cords, by removal of the old cords and the substitution ofnew cords, it is simply necessary to open the section 11 at the bottomof the weight pockets to afford access to the Weights and the cordconnections therewith, and to swing the pivoted closure plate 23 fromits recess to afford access to the internal recess or socket for theknotted ends of the cords whereby they are retained in connection withthe sash. The old cords can then be readily disconnected at theirconnection ends from both the weight and the sash and drawn out ateither of the open terminals. Then, to insert and connect the newsuspension cords, it is simply necessary to pass one end of the cordthrough the slot opening 5 in the window frame and over 7 the pulley 6and feed it down until its end reaches the weight 8, to which it is thenconnected, and the other end of the cord is then fed downwardly in thesash edge groove 10 to the internal recess or socket 18 and through thefront opening thereof, when it maybe knotted in the usual manner andreturned to said recess to form an anchored connection with the sash,after which the pivoted closure plate 23 and the section 11 are returnedto normal position. It Will be noted that, in the improved constructionas comprised in my invention, the supplementary closure plate 23operates in a corresponding recess in the sash stile immediately beneaththe face plate 21 which is countersunk at the face of the stile andflush with the surface thereof and permanently secured thereto, and thatsaid supplementary closure plate is pivoted to swing laterally at theinner edge of the stile to open or close the opening in the overlyingface plate, whereby none of said elements affording access to the stilesocket are projective at the face of the stile either in their securednormal or operative positions. It will be further noted that saidlaterally-swinging under closure plate has the axis of its fulcrum sodisposed that the closure plate will automatically retain its normalposition within its recess in the stile and be concealed beneath theface plate.

Having thus described my invention, I

' claim and desire to secure by Letters Patent:

An improved window construction of the class described, comprising thesash stile having an internal recess forming an anchorage socket for theendof the suspension cord, a face plate countersunk at the face of thestile and flush with the surface thereof and permanently secured theretoand having an opening registering with said internal socket, and asupplementary closure plate operating in a corresponding recess in thesash stile immediately beneath said face plate and pivoted to swinglaterally at the inner edge of the stile to open or close the opening inthe overlying face plate, whereby none of said elements affording accessto the stile socket are projective at the face of the stile either intheir se-' cured normal or operative positions, said laterally-swingingunder closure plate having the axis of its fulcrum so disposed that theclosure plate will automatically retain its normal position within itsrecess in the stile and be concealed beneath the face plate,substantially as and for the purpose set forth.

In testimony whereof I have signed the foregoing specification.
